UNITED STATES PATENT OFFICE.

CHARLES O. GLASCOCK AND JOHN W. GLASCOCK, OF MUNCIE, INDIANA.

CENTRIFUGAL BUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 544,848, dated August20, 1895.

Application filed July 10, 1894.

,To all whom it may concern.-

Be it known that we, CHARLES O. GLAS cocK and JOHN W. GLAsoooK, citizensof the United States, residing at Muncie, in the county of Delaware andState of Indiana, have invented a new and useful CentrifugalButter-NVorker, of which the following is a specification.

Our invention relates to butter-workers, and has for its object toprovide a device of this class adapted to expel the buttermilk bycentrifugal force, to avoid the pressing of the butter by a paddle orotherwise, and hence avoid the breaking or crushing of the grains of thebutter.

Further objects and advantages of the invention will appear in thefollowing descriplion, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a machine embodyingour invention. Fig. 2 is a vertical section of the same. Fig. 3 is adetail, in perspective, of the spider or supporting frame detached.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

1 designates a tub or receptacle in which is mounted a vertical cylinder2, having reticulated sides 3 and an imperforate top and bottom 4 and 5.The sides of the cylinder may be of perforated sheet metal, as indicatedin the drawings, or of wire-gauze or similar material, as may bepreferred, and the removable top 4 is adapted to lit within the upperedge of the sides of the cylinder, and is provided with a shoulder 6 tobear upon the upper edge of the same. The cylinder is mounted in the tubor receptacle with its axis in a vertical position, the bottom beingprovided with a depending trunnion 7 to fit removably in a socket 8 onthe bottom of said tub or receptacle, and the removable top of thecylinder being provided with an angular socket 9, into which lits thesquared terminal or boss 10 at the lower end of a vertical spindle 11.Said vertical spindle is mounted in and supported by a frame or spider12, having the arms 13, which are fitted in recesses 14 in the upperedges of the side Walls of the tub or receptacle and are held in placethere- Serial NoL 517,130. (No model.)

in by means of turn-buttons 15. Said arms are provided upon their lowersides with depending ears 16 to bear against the inner surfaces of theside walls of the tub or receptacle. Said vertical spindleis provided atan intermediate point with a bevel-pinion 17, with which meshes abevel-gear 18, carried by a shaft 19, mounted in bearings 20 upon theframe or spider. This shaft also carries a pinion 21, which meshes withthe teeth of a large driving or master gear 22, mounted upon astub-shaft 23, secured to the side of the tub or receptacle by means ofa plate 2l. This driving or master gear is provided with a handle 25.

In connection with the above-described mechanism we employ a pocket 2Gof fabric or other porous material, which is arranged within the rotarycylinder and which is held in place therein by the engagement of itsedges between the top or cover of the cylinder and the upper edges ofthe walls of the latter, and the butter is placedin this pocket or sackand is thus held in a compact body during the operation of the machine.

From the above description it will be seen that to open the cylinder forthc insertion or removal of butter the supporting frame or spider isdetached by turning the buttons to disengage its arms, after which thetop or cover of the cylinder may be displaced. We also employ a spur orspurs 27 on the upper edge of the walls of the cylinder to engage theupper edges of the pocket or sack and thus hold the same until the topor cover of the cylinder has been properly adjusted, and the said top orcover is provided with a notch or notches to register with and engagesaid spur or spurs to prevent independent rotation of the top or coverduring the operation of the machine.

The above-described mechanism for rotating the cylinder provides for arapid movement of the same, in that the driving or master gear mesheswith a small pinion, and the shaft to which said pinion is fixed alsocarries a large bevel-gear which meshes With a bevel-pinion on thespindle, which is engaged with the socket in the top or cover of thecylinder.

By forming the pocket or sack with sides land bottom to cover the entireinner surface lOO of the cylinder the butter or other material, afterbeing worked, may be removed in the pocket or sack Without difficultyand in one operation. This is of particular advantage in connection witha butter-Working apparatus, and it results in a considerable saving ofthe material. Furthermore, the manner of securing the pocket or sackWhen the machine is in use by engaging its upper edge between the top orcoverand the upper edge of the sides of the cylinder avoids complicationand is effective, the detachment of the pocket or sack beingaccomplished by the same movement which removes the top or cover. Thespurs, Which are arranged at the upper edge of the cylinder, hold theupper edge of the pocket or sack Within reach of the operator or preventit from falling into the cylinder when the lid or cover is removed.These spurs also prevent independent relative rotation of the cylinderand its top or cover, and henceperformadouble function. The'pocket orsack should be arranged in the cylinder with its upper edge engaged bysaid spurs before the butter or material to be worked is introduced.Said arrangement provides for holding the pocket or sack in an openposition to receive the material, and hence dispenses with theassistance of a second person in preparing the apparatus for operation.The application of the lid or cover firmly secures the pocket or sack,and the fact that the upper edge of the pocket or sack vis thus arrangedbetween the sides of the cylinder and the top or cover forms a packingfor the joint. \Vhen the top or cover is removed, the pocket or sackdoes not drop into the cylinder, but is held in place until grasped bythe operator to remove the contents of the cylinder in the sack.

It will be understood that various changes in the form, proportion, andthe minor details of construction may be resorted to without departingfrom the spirit of the invention or sacrificing any of the advantagesthereof.

Having described our invention, what we claim is 1. In a machine of thecharacter and for the purpose specified, the combination of a cylinder,having reticulated sides, and provided at its upper edge with a seriesof spurs, a sack suspended Within the cylinder, and having its upperportion extending over the upper edge of the cylinder, and engaged withthe spurs thereof, a cover for closing the upper portion of thecylinder, and having an outer edge portion to rest upon the top edgeofthe cylinder, and bear upon the upper portion of the sack to retainthe latter in working position, and having notches in its edges tocorrespond in number and position with the aforementioned spurs, wherebythe cover and cylinder are held in locked relation, and drivingmechanism applied to the said cover for operating and rotating thecylinder, substantially as set forth.

2. The herein specified centrifugal butter worker comprising areceptacle, a cylinder journaled therein, and having reticulated sides,and having spurs extending upwardly from its top edge, a sack suspendedWithin the cylinder, and having its upper portion extending over theedge of the cylinder, and engaging with the spurs thereof, a cover forclosing the upper end of the cylinder, and provided in its edges withnotches to receive said spurs and hold the cover and cylinder in lockedrelation, said cover having an outer edge portion to extend over theupper end of the cylinder, a spider, or frame, removably supported uponthe receptacle, and driving mechanism carried by the said spider orframe, and adapted to make connection with the cover for rotating it,and the cylinder, substantially as set forth.

In testimony that We claim the foregoing as our own we have heretoaffixed our signatures in the presence of two witnesses.
